Unlike simple diode logic, the Valentina model utilizes a multi-emitter transistor. This allows for multiple inputs (A, B, C) to control the state of the circuit with minimal components, drastically reducing the physical footprint on a silicon wafer.
As of 2025, the original Valentina project has seen a fragmented evolution, with (a community fork) and Tape gaining traction. However, the underlying TTL paradigm remains intact. New developments include: valentina TTL model
